Zopherus haldemani Horn, 1870:271.—Champion, 1884:43.—Casey, 1907b: 463
This subspecies is apparently a continuation of the trend from the dark (nodulosus) to the lighter (sallaei) form. This is the lightest form of the series and, as Casey (1907b: 463) remarks, is rather constant in coloration. The sutural rows of black blotches are contiguous and form a continuous black band from base to apex. There is also an irregular longitudinal black band on the pronotum. The lateral areas of both pronotum and elytra are predominately white.
Because the constant pattern of coloration appears to be geographic, it seems advisable to retain the trinomial for this and the previous taxon. Most of the specimens seen from north of the Rio Grande River are readily separable from those from Mexico.
